Several aspects of the lattice W-N algebra are studied. Motivated by t
he fact that the Lotka-Volterra model can be written in terms of a cur
rent of the lattice Virasoro algebra (the Faddeev-Takhtajan-Volkov alg
ebra), integrable dynamical models on the lattice have been formulated
as a model associated with the lattice W-3 algebra.
